IMPROVEMENT IN CORN-SHELLERS.

Specification forming part of Letters Patent No. 55,362, dated June 5, 1866.

the letters of reference marked thereon.

In the accompanying drawings, Figure l is a side elevation of the machine. Fig. 2 is a plan view. Fig. 3 is a vertical section in the line no x of Fig. 2; and Fig. 4 is a view of one ofthe concave holders, t', detached.

A is the main frame of the machine. B is a pulley for operating the main shaft B' by means of a belt or strap. C is a cog-wheel mounted on the shaft C', and matching into a cog-wheel, B2, mounted on the shaft B. This cog-wheel G and shaft C are added to the machine for the purpose of operating it by a revolving-shaft power'applied to the said shaft G'; but when the machine is to be run by a belt passing over the pulley B said shaft C' and cog-wheels G and B2 will not be required.

D is a hopper or inclined floor upon which the ears of corn are thrown to be fed to the shelling mechanism. d cl d d are grooves in said inclined door to conduct the ears of corn to the apertures through said floor D' D' D' D', through which they fall to"v4 the shelling machinery.

E E are two wheels mounted on the shaft B', provided with double sets of cogs or teeth b b b on each side, to shell the corn.

i t' t' t' are concave guides and holders to receive the ears of corn as they fall through the apertures D', and hold them up against the wheels E while the corn is being shelled. These concaves are made in the form of sections of cones tapering downward, and are attached to slats, (shown by red lines e e e 6,) and these slats are held in proper positions vrelatively to the wheels E by means of yield- G is an inclined oor upon which the shelled corn falls, and Gr' a slotted screen through which it passes after running down the inclined floor Gr, falling from said screen upon the inclined plane K, by which it is conducted to the exit chute or spout H. Motion is given to said inclined door G and screen Gr' by means of a crank,j, on the end of the revolving fan shaft, the connecting-rod J, and the lever l, having its fulcrum at the opposite side of the machine, and pivoted at its center to the fioor G.

g and g' are guide-boards to gather the shelled corn and guide it to theinclined loor G. The teeth b b b, &c., on the wheels E are neither set radially nor tangentially, but atan intermediate angle, so that as the wheel revolves the outer and forward corner of each tooth will first come in contact with the ear of corn and force it down the concave holder.

I is the opening through which the cobs are discharged, and through which, also, the chaff and dust are blown out by the fan. A

The operation is as follows: The machine having' been set in motion by applying the power either to the pulley B or the shaft C', as circumstances may require, the ears of corn are thrown into the hopper D, and sliding down the grooves l d d d they enter endwise and pass through the apertures D' D D' D', dropping into the concave holders t' t' it', where they are seized by the teeth lof the revolving wheels E E,revolved within said holders, and the grains detached from the cob. The cobs and grain fall together on the inclined ii'oor G, and in passing over the screen G' the shelled corn passes through the same, falls upon the inclined plate K, runs down into the exit-spout H and is discharged therefrom,

while the cobs pass over the screen'and out of the opening' I, the chaff and dust being at the same time blown out of said opening by the fan.

Having thus fully described my invention and its mode of operation, what I claim as'new, and desire to secure by Letters Patent, is-

1. The combination of the double-toothed wheels E, the concave holders t', mounted on slats e provided with yielding springs f, and the grooved hopper D, all constructed and arranged substantially as and for the purposes described.

2. The helical gains l1, in the concave holders t', as and for the purposes described.

3. The teeth upon the wheels E, set at an combination with the apertures D', substanfz i 7 55,362
